The size of the earth or ground wire is based on the______________?
Correct answer: D. both (A) and (C)
- A. maximum fault current carrying through the ground wire
- B. rated current carrying capacity of the service line
- C. depends on the soil resistance
- D. both (A) and (C)
Explanation
Grounding design must provide a safe path for the prospective fault current, while soil resistance affects how effectively the grounding system dissipates that current. Therefore both maximum fault current and soil resistance are relevant in the stated context.
